Hello everyone, I'm reaching out to the community for some specialized guidance on modifying the steering assistance maps on my VW Golf VII. I have a physical condition/disability that significantly reduces my arm strength, making the standard steering feel on my car, even in Comfort mode, quite heavy and tiring to manage, especially during low-speed maneuvers and parking. I've read through this thread and was particularly interested in the experience shared by @Frankenfurter about changing the steering rack parameters using VCP/ODIS to alter the steering assistance levels. This seems like it could be a life-changing modification for me. My vehicle has a steering rack with part number 3Q0909144K (hardware 3Q0909144H, EPS_MQB_ZFELS system). My goal is to achieve an ultra-light steering feel, making it significantly softer than the factory Comfort mode. I would like it to be a permanent setting (not dependent on the driving profile) to ensure consistent and predictable assistance at all times. Based on my research, I understand the process would be: Use VCP to read the current parameterization file from my steering rack. Find a suitable parameter set (SGO file) from a lighter MQB vehicle (like an A3 or Octavia) that has a similar rack and provides a "softer" steering map. Flash this new parameterization using VCP and perform the necessary calibrations (G85, end stops). My specific questions for those who have done this: Compatibility: Has anyone successfully loaded a "softer" map onto a 3Q0909144K/H rack? Are there any known issues or specific firmware versions to avoid? Source of maps: Which vehicle maps (Audi A3, Octavia, etc.) and what "level" numbers would be the best starting point for achieving maximum lightness? From what I understand, lower numbers mean less assistance, so would a higher number provide more assistance (softer)? Procedure: Is the workflow I described (read -> find matching SGO -> flash -> calibrate) correct for my hardware? Are there any specific security access codes or special steps needed for the 3Q0 rack? Risks: What are the main risks involved in this process (beyond the usual flashing risks)? Could this cause any errors in other systems like ESC or ACC? I have access to VCP and a compatible interface. I'm comfortable with the technical process but want to ensure I have all the correct information before proceeding, as this is a critical accessibility modification for me. Any advice, experiences, or pointers to reliable sources of parameter files would be greatly appreciated. Thank you in advance for your time and understanding.
